Since its formation, LEAT has researched and published several papers, training manuals, and reports on natural resources management, human rights, and the environment. The organization has contributed to policy and legal reform processes, including the enactment of Environmental Management Act 2004, the Disaster Management Act 2014, the amendment of the Mining Act of 2010, the Natural Wealth and Resources (Permanent Sovereignty) Act of 2017, and the Natural Wealth and Resources Contracts (Review and Re-Negotiation) Act of 2017;

For the year 2019, through “Examining the legal and regulatory regimes of minerals, gas, and petroleum laws in Tanzania” project, LEAT worked to: (a) increase knowledge on the extractive industry legal and policy regimes in Tanzania and other East African nations by lawyers, journalists, relevant public institutions, CSOs and members of the public; (b) increase knowledge on the transfer pricing abuses mechanisms and how they are addressed or not addressed in Tanzania; (c) transparency in the collection, saving, investment and appropriation of oil and gas revenues; (d) reduce incidences of transfer pricing abuses; and (e) increase ability by Tanzanian lawyers to negotiate beneficial Mining Development Agreements (MDAs) and Production Sharing Agreements (PSAs).

Lawyers’ Environmental Action Team (LEAT) conducted a study on the immediate effects of the Land Tenure Support Programme (LTSP) on communities in Kilombero district (Morogoro). The study aimed to identify the impacts of LTSP, the biggest land regularization programme, to ever be implemented in Tanzania. Funded by DFID and DANIDA, the LTSP was implemented in Malinyi, Ulanga, and Kilombero between 2016-2019 to improve land tenure security through good land tenure regularization.
